Convert ASCII string to Decimal in R (vice versa) was: Hex

Hi Dieter,

Sorry my mistake. I wanted to convert them
into Decimal (not Hexadecimal).

Given this string, the desired answer follows:

ascii_str  <- "ORQ>IK"

79 82 81 62 73 75

ascii_str2 <- "FDC"

70 68 67

For example I have the following ASCII strings:

ascii_str  <- "ORRRIROOQRQQOLORRRRRRQRROKK>IKFAA"
ascii_str2 <- "FFFFFFFFFFDDDDDDDDDDCCCCC>>>>>>>>>"

Each character in the above string represent a hexadecimal value.
I want to translate those string into an array (of size == string length)
which contain hexadecimal conversion.

as.hexmode doesn't seem to do the job.

Trying again, simplified

ascii_str  <- "ORQ>IK"
ascii_str2 <- "FDC"

What do you want as output in both cases? I can partially understand the second
case, but not the first.
